Rain 5G unlimited not reliable

Good day, please note that there is no network in my area. Is it possible to get a “signal booster” or to get another tower just specifically for my area. You have called me before, we have done all the troubleshooting, and your 5G seems to disconnect every now and then and it’s not having a good connection and it’s not fluent. It keeps buffering still, and this happens every week without fail and almost everyday, please offer a signal boost of possible or add a tower, thank you, plus it’s exam time and all these things are done online
